试题六(共15分)
阅读下列说明和Java代码,将应填入 (n) 处的字句写在答题纸的对应栏内。
【说明】
某发票(lnvoice)由抬头(Head)部分、正文部分和脚注(Foot)部分构成。现采用装饰( Decorator)模式实现打印发票的功能,得到如图6-1所示的类图。

【java代码】
class invoice{
public void printInvoice(){:
System.out.println ( "This is the content of the invoice!");
}
}
class Decorator : extends Invoice {
protected Invoice ticket;
public Decorator(lnvoice t){
ticket = t;
}
public void printinvoice(){
if(ticket != NULL)
(1);
}
}
class FootDecorator extends Decorator{
public FootDecorator(lnvoice t){
super(t);
}
public void printinvoice (){
Systent.out.println( "This is the header of the invoice! ");
(2) ;
}
}
class FootDecorator extends Decorator {
public FootDecorator(invoice t):{
super(t);
}
public void printlnvoice(){
(3) ;
Systent.out.println( "This is the header of the invoice! ");
}
}
Class test {
public static void main(string[] args){
Invoice t =new invioce();
Invoice ticket;
Ticket= (4) ;
Ticket. Printinvoice();
Systent.out.println(“--------------“)
Ticket= (5) ;
Ticket. Printinvoice();
}
}
程序的输出结果为:
This is the header of the invoice!
This is the content of the invoice!
This is the footnote of the invoice!
----------------------------
This is the header of the invoice!
This is the footnote of the invoice!
